Going against the grain, I disagree about the crop. I much prefer the original, just as it is. The crop has taken the focus away from the sky + placed it on the sea instead, i.e. the 'dead space' is now in the middle of the shot instead of at the top where it was before. It has, as a consequence, lost the lovely curves of the halo surrounding the sun, which in itself is plenty for me to look at in that beautiful sky. I think it would make a great poster, love it
